See the Cast of 'Mars Attacks!' Then and Now

In 1996, Tim Burton unleashed 'Mars Attacks!' on audiences, a sci-fi comedy featuring an amazing ensemble cast including the likes of Jack Nicholson, Natalie Portman and Pierce Brosnan. A riff on classic B-movies and based on the cult trading cards of the same name, the film tells the story of a group of martians who attack our planet and the unlikely hero who discovers the very silly way to destroy them. (Hint: it involves country music). We can't believe it's already been 17 years since the film first hit theaters, so join us for a look back at its all-star cast and see what they're up to now!
